Monochrome Parallel mode on STM32F401 & F411 - flickering #19

Closed board707 closed 1 year ago

Found numerous artefacts and flickering in Monochrome Parallel mode on boards STM32F401 & F411 in 0.8.0 - 0.9.0 releases. Debugging in progress, Use Monochrome SPI mode for now.

The speed of the library on the STM32F4 boards seems to be too fast for monochrome matrices. Adjusting timings resolve the problem.

Fixed in v.0.9.2
